• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (hieu lang)) - hanh trung ha phuong dong van ((toan tap) OR (van ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (hieu lang)) - hanh trung ha phuong dong van ((toan tap) or (van ban))".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (hieu lang)) - hanh trung ha phuong dong van ((toan tap) or (van ban))*.
